Product Overview
JVR-384 overvoltage and undervoltage protector is mainly used for AC 50/60Hz, rated voltage below 460V, industrial three-phase 220V, 380V, 440V, 460V and other voltage levels of various fault detection. It provides relay protection for high voltage and low voltage of three-phase input power.
Features:
1. Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc.
2. Such as central air conditioning compressor protection, power monitoring of various elevators, phase loss of pumps and oil pumps, reverse phase protection, etc.
4. Installation method: The base of the protector adopts the rail type, and there are two M4 screw holes in the structure, which can be directly installed separately or installed on the HT35 rail.
5. Indicators: Indicated by three indicators: normal, overvoltage, undervoltage.
8. This product complies with the GB14085.5-2001 eqv IEC60947-1:1999 standard.
Specification:
Condition: 100% Brand New
Dimensions: Approx. 68 x 30 x 76mm / 2.7 x 1.2 x 3in
Main Circuit:
2) Connecting wires of the main circuit: The insulating copper wire has a carrying area of 1.0 to 2.5 mm. If a single strand of copper wire can be directly inserted into the terminal; if a cord is used, a needle type terminal must be added to the wire to ensure reliable connection.
Auxiliary Circuit:
1) A normally open and a normally closed contact that is electrically inseparable.
2) Use Category: AC15, DC13
3) Contact Capacity: 250VAC 2.5A, 30VDC 1.5A
Conventional Thermal Current: 5A
Default Factory Setting: Overvoltage protection +15%, undervoltage protection -15%.
T with the back -- Overvoltage & Undervoltage setting is based on customer requirements.
Package List:
1 x User Manual
Note:
2. This product is generally sampled on the power side of the three-phase power supply and must not be installed on the output side of the variable frequency current.
3. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.

Features
1、Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc.
2、It is an indispensable protection product for the normal working voltage of the maintenance equipment in the operation of industrial equipment.
3、Indicators: Indicated by three indicators: normal, overvoltage, undervoltage.
4、Overvoltage protection: It means that the voltage of the protected line is higher than the set value, the delay is 3~8S, and the recovery is 6~20VAC.
5、Undervoltage protection: It means that the voltage of the protected line is lower than the set value, and the delay is 3~8S, and the recovery is 3~20VAC.
